When making a cross-domain Ajax POST request, AngularJS sends an HTTP OPTIONS request first. jQuery does the same, and I understand this is part of the spec. The difference is if there's an error with the OPTIONS request (e.g. server doesn't support it, as is often the case) jQuery will continue and make the POST request anyway where AngularJS just silently fails and gives up. Is there a way to force it to make the POST request regardless ?
As Guillaume86 said the OPTIONS request (aka preflight CORS request ) is sent by the browser if the request is made cross domain. See here the specs http://www.w3.org/TR/cors/ . The browser will cache it if you set a cache header. E.g :
